Considering the problems such as long duration of defrosting, low working reliability and high energy consumption of refrigerated containers, this paper put forward a new defrosting method combining air and electro-thermal energy, and designed a new defrosting structure system based on the structural features of refrigeration modules of refrigerated containers. The two-variable method of wind pressure change and temperature difference change on both sides of the evaporator was used to detect frosting, and the specific controlling strategy supporting the new defrosting system was provided to realize the effect of intelligent defrosting. It can provide references for fast defrosting, intelligent defrosting and low energy consumption defrosting of refrigerated containers.

With the rapid development of the national economy, an effective way is urgently anticipated to unburden the pressure of low resources utilization, high energy consumption and serious environment pollution resulting from industry solid waste. In the present paper, a new process by applying atomization technique into disposing of melting slag is proposed for highly effective utilization of solid waste. It is characterized as simultaneous completion of super cooling and fine pulverized, and improvement on utilization efficiency of melted slag for increase of activity and saving of milling energy. This method is believed to be a new available approach to greatly promote the development of our recycling economy

Spray drying is a kind of unit operation with high energy consumption and relatively low energy utilization, and the problem of low thermal efficiency has been attracted the attention by scholars at home and abroad. The factors affecting the thermal efficiency of spray dryer are analyzed. From a technical point of view, the thermal efficiency of spray dryer can be increased through the unit operation. Measurements for the reduction of energy saving of spray dryer were put forward.

Rapid development around the globe, increase of population and construction with the latest and megastructures have escalated the demand for energy. The increasing of ambient outdoor temperature requires mechanical air conditioners to maintain a comfortable environment within the building, this contributes to high energy consumption. Building with good thermal conductivity properties passively reduces energy consumption. This experimental work focuses on four (4) brick systems which are Laterite Clay (LC), Solid Waste Fly Ash (SWFA) Bricks, Laterite SWFA (LS) Brick, and Laterite SWFA Paint Sludge (LSP) Bricks. Ordinary Portland Cement (OPC), Hydrate Lime (HL), and Ground Granulated Blast Furnace Slag (GGBS) were used as stabiliser. Higher thermal conductivity was recorded for all bricks systems that stabilised with HL. Thermal conductivity was significantly reduced when GGBS was incorporated as a blended stabiliser. SWFA bricks system recorded the lowest thermal conductivity of all bricks systems investigated. A lower thermal conductivity value indicates better thermal properties. In all brick-wall systems, the thermal conductivity was found to increase linearly with density.

The rapid development of China’ s economy and society is obtained at the cost of the consumption of energy, especially fossil energy. And the coal-based energy consumption structure enables China to become the largest carbon dioxide emitter in the world. With the enhancement of global greenhouse effect, ecological environment deterioration is becoming increasingly serious. Carbon emission reduction has become one of the most important international issues. As one of the fastest growing economies in the world, China has also actively responded to energy conservation and emission reduction.As a major energy province in China, Shaanxi province plays a critical role in the national energy supply, and it was also listed as the first batch of low-carbon pilot areas in 2010. In recent years, relying on its own energy advantages, Shaanxi has witnessed rapid economic growth, but the resource stock and environmental carrying capacity cannot withstand the high intensity of resource consumption and environmental pollution under the traditional resource mode. As the first batch of “low-carbon development” pilot provinces, adjusting the industrial structure, changing the mode of economic development and realizing “low-carbon economy” have become the urgent problems to be solved in Shaanxi Province.

With the rapid economic development, the transportation sector becomes one of the high-energy-consumption and high-CO2-emissions sectors in China. In order to ensure efficient use of energy and to reduce CO2pollution, it is important to gain the best performance standards in China’s transportation sector. Data envelopment analysis (DEA) has been accepted as a popular tool of efficiency measurement. However, previous studies based on DEA are mainly restricted to the radial expansions of outputs or radial contractions of inputs. In this paper, we present a nonradial DEA model with multidirectional efficiency analysis (MEA) involving undesirable outputs for the measurement of regional energy and environmental efficiency of China’s transportation sector during the period 2006–2010. We not only evaluate the energy and environmental efficiency level and trend of China’s transportation sector but also investigate the efficiency patterns of 30 regions and three major areas of China. Additionally, we identify the energy saving potential and CO2emissions reduction potential for each province and area in China in this study.

Metallurgy industry is an important part of national economy, thereinto, steel enterprise is the most important part, and it has become a significant symbol of comprehensive national strength. According to the analysis, in the Large and medium-sized Steel enterprise the effect of energy saving and emission reduction is obvious, But the process equipment behind of small and medium-sized enterprises, high energy consumption and discharge many pollutants. In order to reach require, Electrical precipitator has been widely used. In this text, we make comprehensive narrative for metallurgy industry characteristics of flue gas, and analyze the affect of flue gas to electrical precipitator, finally, we put forward some constructive measures and suggests.

With the rapid development of information technology, there are more and more computer rooms with power consumption. In this paper, we study the main problem that the present status of high energy consumption in data centers, we put forward the room resource dynamic scheduling problem. According to the approximate dynamic programming ideas of modeling room resource dynamic scheduling model is established, to solve the problem of heuristic rules. To meet the demand of the outside world, it reduces the condition of lower energy consumption, making for a period of time to achieve maximum room revenue.

With the datum of output, energy consumptions and environment pollutions of 36 industries of HeBei Province during the period of 2005-2007, we first calculated the marginal values of GDP contributions, energy consumptions and environment damages each industry played on the whole provincial economy. Compared with the average values, the industries were further divided into four groups with the method of Four Quadrants, which are the ones of (High-Growth-Contribution, High-Energy-Consumption or High-Pollution), (Low-Growth-Contribution, High-Energy-Consumption or High-Pollution)), (Low-Growth –Contribution , Low-Energy-Consumption or Low-Pollution), (High-Growth–Contribution , Low-Energy-Consumption or Low-Pollution). Based on this division, we put forward the suggestions of structural adjustment for each group of industries in views of sustainable development.

Many residents are superstitious so-called high-tech residential, see the technology will bring the thermal comfort, in fact, some high-tech residential only additional high-grade HVAC facility, the thermal comfort should not advocate in the northern Jiangsu area, after all, this is a high energy consumption of thermal comfort. In the north of Jiangsu Province, should promote low energy consumption of thermal comfort residential.
